difference between EN ISO 20471 and EN 471fluorescent standard fluorescent clothing
As of October 1, 2013, the European Commission has decided that EN ISO 20471: 2013 "High Visibility Apparel - Test Methods and Requirements" will supersede EN471: 2003 + A1: 2007 "Dedicated High Visibility Warning Tester - Test Methods and Requirements" as New harmonized standard for EU safety fluorescent clothing. As of October 1, 2013, all EEC certificates of safety reflective clothing tested to EN471 will be ineffective; all safety fluorescent clothing shall comply with the requirements of EN ISO 20471: 2013 prior to its launch in the European Union.
Upon request, the main differences between the new EN ISO 20471: 2013 Fluorescent Standard and the old EN471: 2003 + A1: 2007 standard mainly include the following seven aspects:
First, the cleaning cycle should meet the color and brightness requirements;
Second, color perspiration perspiration stain staining requirements from 3 to the lowest 4;
Third, the tensile strength of woven materials required to change to a minimum of 100 cattle;
Fourth, the rupture strength of knitted material requirements to at least 100 kPa (50 square centimeters of test area) and a minimum of 200 kPa (7.3 square centimeters of test area);
Fifth, the physical performance test of single-layer or multi-layer clothing, the breathability index (RET) can not be more than 5 square meters per watt, if the air permeability index exceeds 5 square meters per Watt, it must measure and determine imt≥0.15;
Sixth, there is no distinction between the performance levels of reflective materials, the same requirements as Level 2 of EN 471;
Seventh, the new logo changes.
